Benefits of technology

The single-handle design reduces user fatigue, allows for deeper hole digging, and facilitates easier handling of heavy loads, making the tool more comfortable and efficient for solo or shared operation.

Problems solved by technology

Despite the many improvements to post hole diggers over the past century, most post hole diggers on the market today utilize a two handle design and offer many disadvantages to the end user.
First, using two handles forces a user to spread their arms at an uncomfortable distance when thrusting the digger into the ground and when removing soil.
This puts a user's arms, back, and neck into an unnatural position causing fatigue and stress to the body.
The two handle design also makes it difficult for more than one person to operate the digger.
Second, traditional post hole diggers require a great deal of effort by the user to maintain the blades in a closed position while removing heavy loads of soil.
Third, the depth of a hole is limited by the design of traditional two handle post hole diggers which require the two handles to be spread apart by a certain degree in order to open or close the blade members.

Abstract

The present invention is directed to a single handle post hole digger. The single handle of the post hole digger includes an outer elongated vertical handle and an inner elongated vertical shaft that is located within the outer handle. The post hole digger includes two blades used to cut into the ground and to loosen soil when open and then used to capture and remove soil when closed. The single handle configuration allows for deeper holes as the holes do not have to accommodate the opening action of the handles as in traditional diggers.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a new type of post hole digger and more specifically to a light-weight, single handle post hole digger.BACKGROUND[0002]Post hole diggers known in the art are generally configured with two elongated handles connected to two blade members through a pivoting joint. To operate a traditional post hole digger, a user holds one elongated handle in each hand and thrusts the post hole digger into the ground to loosen the soil and then uses the two elongated handles to close the two blade members thereby capturing and holding the soil. The user next removes the post hole digger containing the captured soil out from the hole and opens the handles allowing the soil to fall outside and away from the hole.[0003]There have been many improvements and adaptations to post hole diggers over the years. For example, U.S. Pat. No. 7,798,545 discloses a post hole digger comprising two uniquely shaped elongated handles connected to a blade assemb...
